I have a Fanuc Tape Cut Model M wire EDM machine here in the UK. They seem quite a rare beast. I have found very similar machines on youtube of a similar vintage but called ELOX Fanuc - an example here:

Was it a licencing deal similar to Bridgeports being sold here to their design but locally made?
